What’s the Difference Between Flat Rooflights, Pitched Rooflights, and Roof Lanterns?
Flat rooflights are designed for flat or low-pitch roofs (usually under 15°). They require a minimum pitch to prevent water pooling. Frameless units create a sleek, modern look and let in maximum natural light.
Pitched rooflights are angled to follow the slope of a traditional roof, typically between 15°–70°. They blend seamlessly into tiled roofs and are ideal for loft conversions or upstairs rooms.
Roof lanterns are raised structures that project above flat roofs, like a mini glass conservatory on top of your home. They offer a dramatic architectural feature and flood interiors with light from multiple angles.
Which Type of Rooflight Is Best for My Home?
It depends on your roof type and the look you’re going for:
- Flat rooflight – Best for extensions, kitchens, or modern flat roof designs.
- Pitched rooflight – Ideal for loft conversions or anywhere with a sloped roof.
- Roof lantern – Perfect for adding elegance and height to open-plan spaces like dining rooms or orangeries.
Pro tip: Flat rooflights are more discreet and modern. Roof lanterns add a wow-factor. Pitched rooflights are all about blending in seamlessly.
